SVG Fundamentals
A single SVG circle is rendered centered at coordinates (50, 50) with a radius of 50, demonstrating the basic structure of an SVG element within an HTML page. The example uses plain SVG markup directly in the document, with no JavaScript or CSS styling applied. It serves as a minimal introduction to SVG fundamentals, showing how the `circle` element and its `cx`, `cy`, and `r` attributes define a shape's position and size. The code is a bare HTML file, with no external libraries or frameworks involved.
